Former First Round Pick Nikola Topić Makes NBA Debut After Testicular Cancer Battle

In a moment that transcended sports, Nikola Topić stepped onto the NBA court for the first time on Thursday, 12 February 2026, earning a thunderous standing ovation from the Paycom Center crowd.

The 20-year-old Serbian guard, selected 12th overall by the Oklahoma City Thunder in the 2024 Draft, had overcome a torn ACL and testicular cancer to realise his dream. Checking in against the Milwaukee Bucks, Topić notched an assist on his very first possession, symbolising resilience amid the defending champions' push for a repeat.

From Draft Darling to Injury Setbacks

Topić's journey to the NBA was anything but straightforward. Hailed as a 6-foot-6 playmaker with exceptional vision and handles, he shone in Serbia's Mega MIS and on loan at Crvena Zvezda, averaging 18.6 points and 6.9 assists in the ABA League.

Yet, a partial ACL tear in May 2024 sidelined him for his entire rookie season, forcing the Thunder to stash their prized prospect. As he ramped up for 2025-26, participating in Summer League and one preseason game, fate dealt another blow.

The Shock of Testicular Cancer Diagnosis

In late October 2025, shortly after preseason, Topić underwent surgery that confirmed testicular cancer. The diagnosis stunned the basketball world; at just 20, he faced chemotherapy, completing treatment by early January 2026.

Topić credited his family's support and the Thunder's medical team post-diagnosis, vowing to come back even stronger when he began chemotherapy last October 2025. Testicular cancer, often curable if caught early, required vigilance, but his youth and fitness aided his swift return.

He missed the season's first 55 games, using the time to rebuild strength mentally and physically.

G-League Grind: Proving Readiness

Cleared in mid-January, Topić joined the Thunder's developmental team, OKC Blue, for conditioning. His G-League debut on 10 February was electric: 22 points, six assists, and four rebounds in 19 minutes, showcasing his burst and court IQ.

Coach Daniel Dixon praised his 'tremendous resilience,' noting how Topić handled adversity with poise. These outings—two in total—served as a bridge, ensuring he was NBA-ready without risking further injury. Fans and analysts buzzed: could this 'jumbo playmaker' be the missing piece for OKC's title defence?

Emotional Debut and Fan Adoration

Against the Bucks, 'Loud City' erupted as Topić entered with 1:55 left in the first quarter. The ovation, captured in viral clips, reflected collective admiration for his perseverance.

'What a moment,' tweeted fans, with one calling it 'inspiring.' Topić's immediate impact—an assist—drew cheers, though his minutes were limited. Thunder general manager Sam Presti lauded his 'unwavering spirit,' while teammates like Shai Gilgeous-Alexander welcomed him as a rotational boost.

Looking Ahead: A Bright Horizon

Topić's debut isn't just a comeback; it's a testament to modern medicine, personal determination, and the supportive framework of professional sports. As the Oklahoma City Thunder, boasting a formidable 42-13 record, set their sights on the playoffs, his gradual integration promises to add valuable depth to an already star-studded roster.

For Topić, who already possesses a championship ring from OKC's triumphant 2025 title run—despite not suiting up that season—this milestone heralds a fresh chapter brimming with potential. His remarkable story extends far beyond the hardwood, serving as a powerful inspiration to athletes and non-athletes alike, underscoring the fragility of life and the extraordinary power of grit in overcoming seemingly insurmountable obstacles.
